The recommended tire pressure for most passenger cars is 30 to 35 psi. Check your owner’s manual for specific vehicle specifications. Proper tire air pressure reduces tire wear, provides a smooth ride, and boosts fuel efficiency. Always measure the pressure when tires are cold for the most accurate reading.
Under-inflated tires can lead to reduced fuel economy and increased tread wear. Conversely, over-inflated tires can cause a harsh ride and may increase the risk of a blowout. Regularly checking tire pressure, at least once a month, is essential. Temperature changes can affect PSI levels. For every 10-degree Fahrenheit drop, tire pressure decreases by about 1 PSI.
To achieve optimal performance, ensure that you inflate tires to the manufacturer’s recommended PSI when the tires are cold, preferably before driving. This practice promotes better vehicle handling and safety.
In the next section, we will explore the consequences of improper tire inflation and discuss how to maintain ideal tire pressure throughout the year.
